Appendix B: Reference Information 395
DIVIDE BY 0
• You attempted to divide by zero. This error is not returned during graphing.
The TI-84 Plus allows for undefined values on a graph.
• You attempted a linear regression with a vertical line.
DOMAIN
• You specified an argument to a function or instruction outside the valid range.
This error is not returned during graphing. The TI-84 Plus allows for undefined
values on a graph. See Appendix A.
• You attempted a logarithmic or power regression with a
LX or an exponential
or power regression with a
LY.
• You attempted to compute
GPrn( or GInt( with pmt2 < pmt1.
DUPLICATE You attempted to create a duplicate group name.
Duplicate Name A variable you attempted to transmit cannot be transmitted because a variable
with that name already exists in the receiving unit.
EXPIRED You have attempted to run an application with a limited trial period which has
expired.
Error in Xmit
• The TI-84 Plus was unable to transmit an item. Check to see that the cable is
firmly connected to both units and that the receiving unit is in receive mode.
• You pressed
É to break during transmission.
• You attempted to perform a backup from a TI.82 to a TI-84 Plus.
• You attempted to transfer data (other than
L1 through L6) from a TI-84 Plus to
a TI.82.
• You attempted to transfer
L1 through L6 from a TI-84 Plus to a TI.82 without
using
5:Lists to TI82 on the LINK SEND menu.
ID NOT FOUND This error occurs when the SendID command is executed but the proper
graphing calculator ID cannot be found.
ILLEGAL NEST
• You attempted to use an invalid function in an argument to a function, such as
seq( within expression for seq(.
INCREMENT • The increment in seq( is 0 or has the wrong sign. This error is not returned
during graphing. The TI-84 Plus allows for undefined values on a graph.
• The increment in a
For( loop is 0.
INVALID
• You attempted to reference a variable or use a function where it is not valid.
For example,
Yn cannot reference Y, Xmin, @X, or TblStart.
• You attempted to reference a variable or function that was transferred from the
TI.82 and is not valid for the TI-84 Plus For example, you may have
transferred
UnN1 to the TI-84 Plus from the TI.82 and then tried to reference
it.
•In
Seq mode, you attempted to graph a phase plot without defining both
equations of the phase plot.
•In
Seq mode, you attempted to graph a recursive sequence without having
input the correct number of initial conditions.
•In
Seq mode, you attempted to reference terms other than (nN1) or (nN2).
• You attempted to designate a graph style that is invalid within the current
graph mode.
• You attempted to use
Select( without having selected (turned on) at least one
xyLine or scatter plot.
